Components

## Media Embeds

Create responsive video or slideshow embeds based on the width of the parent by creating an intrinsic ratio that scales on any device.

#### Example

Wrap any embed like an `<iframe>` in a parent element with `.embed-responsive` and an aspect ratio.
The `.embed-responsive-item` isn’t strictly required, but we encourage it.

###### Code Example

    <div class="embed-responsive">
      <iframe class="embed-responsive-item" src="..." allowfullscreen></iframe>
    </div>

#### Aspect Eatios

Aspect ratios can be customized with modifier classes. By default the following ratio classes are available.

Class Reference | Value
--- | ---
`.embed-responsive-{value}` | 21by9 | 16by9 | 4by3 | 1by1

Uses Example

    <div class="embed-responsive embed-responsive-16by9">...</div>
